Media and Virtual Worlds--Virtual Labs research project, media technology like streaming media but also content production, reception and the media business.

Internet technology--Internet technology deals with collaborative software (like wikis), blogging, search engines etc. All technologies which are only possible through the use of the internet..

Social Systems--A collection of all things social, e.g. social structures in software development, a programming guide and reference to successful mobbing (under construction) etc. Or strategies to survive a seemingly endless review cycle and come to results.

university--My work at the Computer Science and Media (CS&M) faculty at Hochschule der Medien

In this post-Snowden area we are taking a close look at secure software, critical infrastructures and ways to conquer the threats to critical infrastructures and individual exposures. Specialists from 1&1, Bosch and mpc are joining us for this long overdue event.

Is the future of games in virtual reality? What is the current state of VR? How does it feel to play a game made for the Oculus Rift? (In case you don't own one: how about building your own? Take a look at the latest gadget from Google I/O . How does it feel to develop a game for virtual reality? Get some background information and
practical know how at this games day. And discuss your vision of the future with us. Please notice the change in the agenda: we'll let you watch another game at the end (:-)

Get a better understanding of your visitors! Learn how to collect and analyse behavioral data. Meet tool vendors and users of analytic tools and learn how to test your business profile.

What can you learn from looking at search requests leading to your platform? You are running youtube videos - did they help to increase the number of visitors? There are many things you can learn from analysing the
behavioral data of your visitors. But before you can do so, you must collect the data and learn to use the tools needed for analysis and reporting. They are a must for a successful site or blog. In case you are just a user of internet sites, you can get a better understanding of data collection on the web and why it is - to a certain degree - absolutely necessary for sites.

Talks and discussions on current legal affairs around the Internet. Intellectual property rights, escpecially software patents, the NSA and Anonymous and last not least the Redtube streaming scandal. In all these cases, technological opportunities meet economic stakeholders on the battle field of laws and legal actions. And not every technology is legal and not every legal claim is justified.

This week I realized, that splitting up requests into tens or hundreds of subrequests is still a rather hard problem, due to the long-tail distribution of response times. A portal is a typical fan-out architecture. In 1999 I found some solutions for fan-out like controlled backends, replication and incomplete (tainted) requests. Google of course goes much further today.

Strictly timed requests, distributed loads and a close look at everything from the CPU over network buffers, data structures in memory etc. are in the toolbox.

You think milliseconds is fast? Think again. Think about putting algorithms into FPGAs. Think about creating algorithms that fit into L1 caches. Algorithms which do not need much memory and which do not touch data more than once. Learn about the use of one-pass algorithms from HFT. And start thinking about all the places in our computing infrastructure, where latency hides.

Is the Internet a good model for power grids? What can energy engineering learn from IT and what should it better do in its own ways? Which patterns work in both areas? What makes a robust solution? This is a short talk on some ideas gained from the Smart Grids Week in Salburg this year. Cultural and technical aspects are covered in my talk on Blackout - on the role of IT in Smart Energy Grids .

Experiences with Model-Driven Architecture in a large Project

Christian Teutrine, Senior Managing Consultant with Global Business Services, IBM will give a talk on practical experiences with MDA, made in a large project which took 7.5 years from the concept phase to the go-live. 80% of the code had been generated. Mr. Teutrine had the role of a business lead architect in this project, and in his talk, he will look at it from a business architecture point of view: How does MDA influence the contractual situation? The project management? Can agile methods be used with MDA? How well does it work over the years? What if off-shore employees join the project?

This talk is a rare chance to get first-hand experience on the interplay between business and technical aspects in a really large project. It is not so much a technical talk.

It was more than time for a re-structuring and renovation of my site. I considered changing to wordpress but finally decided to stick
with my xml-based generative approach. But instead of generating my own navigation I am now using CSS3 (without any javascript) for it. Now comes content cleanup...
